Harry Potter actor Jamie Waylett has been sentenced to two years in prison for being part of a violent mob which took to the streets during last summer's riots in London.

Waylett, 22, who played Hogwarts bully Vincent Crabbe in six of the films, was found guilty of violent disorder by a jury at London's Wood Green Crown Court.

The actor, who had already admitted swigging from a stolen bottle of Champagne during the rioting, was cleared of intending to destroy or damage property with a petrol bomb he was pictured holding.

He already has a previous conviction for cannabis possession.

Waylett, of Hillfield Road, north-west London, was with a gang of at least four people who went into Chalk Farm on August 8, the third night of violence in the capital. He was captured on CCTV at various points during the evening, often with his hood over his head.

Judge Simon Carr sentenced the actor to two years for violent disorder and 12 months for handling stolen goods, to run concurrently. Jailing him, the judge said: "The footage shows you in the near vicinity of a Sainsbury's in Camden which was being looted.

"You were pictured on a number of occasions with a bottle full of petrol with a rag as a wick.

"I accept entirely the jury's verdict that you did not throw or have any intention of throwing it, but merely being in possession of it would have been terrifying to anyone who saw you."

Waylett's defence lawyer, Emily Dummatt, said earlier her client had become a "withered actor by the age of 22".

In mitigation she told the court: "Although he had the good fortune to be in the Harry Potter films, it turned out to be not so good fortune."
